>>38438914Okay, let me put it this way, as I was in this dilemma a few months ago while resetting my SoulSilver copy.
I hadn't played the game in years, and had multiple events that I wouldn't get back, like the Arceus event or the Pokéwalker courses and the Spiky Pichu. However, I wasn't playing the game for that, I was playing it for completion and battling sake. Sure, I had old Pokémon, but the truth was I didn't care much anyways, as they were there when I was 12 and I hadn't looked at them for years. I still have the memories of playing with them, but I don't actually have them. It's like saving old clothes or awards or pictures. If you look at it, and it doesn't bring you happiness or utility, why does it have to stick around? I guarantee you you'll get more enjoyment out of starting again and playing genuinely as opposed to flying through it like you were 10 years younger or keeping the save.
